Working on a research project on refugee mathematicians, Hans Lausch (Department of Mathematics, Monash University, Melbourne) is seeking help from the New Zealand mathematical community. He is interested in obtaining information about the mathematician Peter Dschenffzig.

In 1940, Peter Dschenffzig was transported from England to Australia on the notorious HMT Dunera, as one of about 2000 refugees. Most of those had left Germany or Austria, following harrassment and persecution. Subsequently, Peter Dschenffzig was interned in Hay, NSW; and then he was transferred to a camp in Tatura, Victoria.

Felix Behrend, who had also been on the Dunera and later worked at the University of Melbourne, conducted mathematics courses for the internees. As a result, a few internees could get into the University of Melbourne to begin or to continue their mathematics studies. Among about 40

entries, the name Peter Dschenffzig occurs on the class lists that Behrend kept during the camp schools.

A former Dunera transportee remembers: "Peter Dschenffzig returned to England, became Lecturer of Mathematics (London School of Economics - I think), then took a similar job somewhere in South Africa. He left there a few years later and became a lecturer at a New Zealand University. We had been very good friends at Tatura, and then I lost track of him. One day, probably about 16 years ago, he came through Melbourne on a trip, found me in the phone book and came to see me for a couple of hours. That is how come I know a little of his history - but I have not seen or heard of him since."

Can anyone help with further information?

Leigh Christensen learned the Maori tradition of carving totara poles. Later, he examined Charles Babbage's designs for his Calculating Engines (from books in the Rare Book Room of Auckland Public Library, and other reliable sources), and he was much impressed by the beauty of those engineering designs. In November 1994, the Oedipus Rex Gallery in Auckland mounted a small exhibition of 6 works by Leigh Christensen, each carved from totara, kauri or matai, with some metal machine parts incorporated. Five of the works are inspired by Charles Babbage's designs, combined with traditions of Maori art. That exhibition was extensively and favourably reviewed in the NZ Listener, the NZ Herald and several other magazines and newspapers. The Department of Computer Science at the University of Auckland has bought two of Christensen's works, which are now exhibited in the departmental foyer. "The Difference Engine", inspired by Babbage's Difference Engine No.1, is a carved kauri pole nearly 2 metres high, crowned by a Volkswagen cylinder head.

"BESSIE" is inspired by Howard Aiken's Harvard Mark 2 computer "BESSIE", operating with electromagnetic relays. The sculpture is a carved kauri pole, and amongst the relays there is depicted the eponymous "bug" which was found to have been squashed in a relay, thereby making the computer malfunction. Another work at the exhibition was purchased by a Teaching Fellow here; and the exhibition has resulted in the artist receiving some commissions for further works.
